ABSTRACT:
The present invention provides, inter alia, novel fluorinated polyurethane elastomers (e.g., fluorinated thermoset polyurethane elastomers and fluorinated thermoplastic elastomers) prepared from polyether prepolymers formed from mono-substituted fluorinated oxetane monomers (FOX monomers) and tetrahydrofuran (THF). In addition, the present invention provides methods of making such fluorinated polyurethane elastomers.
